<p class="SectionBody">Checks by snmp v1, v2c or v3 :</p>
<p class="SectionBody">- Memory and swap usage on Linux given by Net-snmp.
<br>
It checks memory and swap usage independantly : one warning and
critical level for each of them.<br>
</p>
<p class="SectionBody">- Memory usage on cisco routers or Pix : the
plugin will add all of the memory pool and then checks the warning
and critical levels.<br>
On cisco routeurs, it will add 'IO' and 'Processor' memory<br>
On Pix, it will check the memory used (one memory pool only on Pix).<br>
</p>
<p class="SectionBody">- Memory usage on HP Procurve switch.<br>
Memory segments will be added then the free memory will be checked.<br>
